Guess My H.P. ?

New to Raptors but not to building quads and wanted a guess as to the HP this is making:
01 660

11:1 CP Stock bore
HC2
Yosi Exhaust
Pro Designs w/ K&N
Professionally Ported Head (do the pictures look like it's more than mild porting?)

Also wondering if a HC3 might be better suited? Hp increase from the HC2?

It will be ridden in the Oregon Dunes, so drag racing and tree shots at Sandlake and Banshee hill in Winchester will be most of its life.

Thanks,

Tim @ Clutchmotorsports
